Platform-wagon gear



UNITED STATES PATENT OFFICE.

OLIVER VANORMAN, OF RAOINE, WISCONSIN.

'PLATFORM-WAGON GEAR.

SPECIFICATION forming part of Letters Patent No. 247,443, dated September 20, 1881. Application filed June 11, 1881. (Model) To all whom it may concern:

Be it known that I, OLIVER VANoRMAN, of Racine,in the county ofRacine, and in the State of Wisconsin, have invented certain new and useful Improvements in Platform Wagons;

and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to platform-wagons of that class in which there is a hinged connec tion between the body and front gear, and will be fully described hereinafter.

In the drawings, Figure 1 is a plan view of the front gear of my platform-wagon. Fig. 2 is a vertical cross-section of the same, taken on the lineyy; and Fig. 3 is a longitudinal vertical section taken on the line no a: of Fig. 1. Fig. 4 is a bottom view of the oscillating plate, and Fig.5 is a detail sectional view.

Like letters refer to the same parts in all the figures of the drawings.

Ais what is termed a platform in the class of wagons to which my invention applies, and the platform A carries the usual circle, A, supported on the curved pieces A A and crosspiece B. The center piece,B, of the platform assists in supporting the cross-piece B, which is re-enforced at b, and is provided with a hub, b, in which is a hole for the king-bolt to pass through. The top of the re-enforce is flattened about the hub b to afford a bearing for the center of an oscillatingplate, O, which is reamed out at c to admit the hub 11, and is slotted at d to allow the king-bolt D to pass through it. The under side of the oscillator-plate O is beveled toacentral apex, which forms its hearing when the front wheels of the wagon are on a level with each other; but when one of the front wheels is elevated by an obstruction the platform will tip up, and, instead of raising that side of the body, will merely change its point of contact with the plate 0 from the ridge or apex 0n the bottom of the plate to one of its sides, the slot (1 in plate 0 allowing the king-bolt D sufficient lateral play to prevent any strain on the body, even when the axle is tilted to an angle of forty-f1 ve degrees.

The oscillator plate 0 is provided at each end with a pair of lugs, E E, in which arejournaled rollers E, generally flanged, as shown, and these rollers travel on the circle A, their flanges tending to hold them in place and to relieve the king-bolt of lateral strain.

An ordinary T-bolt, secured to the upper side of the oscillator-plate,serves as a medium for connecting it with the wagon-body.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination, with the front gear of a platform-wagon having re-enforced center piece, B b, and hub 11, of a circle, A, and an oscillator-plate, G, carrying rollers at each end, and formed with a beveled bearing on its under side and a cone-shaped socket adapted to fit over the hub 12, as set forth.

2. The oscillator-plate G, beveled to a knifeedge on its underside at the center, and provided with a cone-shaped socket and a beveled slot to receive the hub and king-boltof aplatform gear respectively, as set forth.

3. The combination, in a platform-wagon, of the circle A, oscillator-plate 0. having rollers E at each end, and beveled under side bearing, conical socket, and beveled slot atits center, with the cross-piece B, having re enforce band hub 11, and the king-bolt D, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 27th day of May, 1881.

OLIVER VANORMAN.
